Re: EOS New PowerShot S2 IS

I''m going to guess that since 35mm P&S lenses are smaller too, the same 
design problems exist for ultra-wides that Matt originally cited.  I would 
think, although I'm no expert, that there are two factors - the first is 
simply the physical size of the lens, and the associated problems of 
minimizing distortion and diffraction, the second being the size of the 
image area, which in the case of digital simply exacerbates the first 
problem.  If it WERE simply a marketing thing, there would be some 
specialized example out there that was out of 90% of our budgets.

You're ignoring the fact that most (almost all) 35mm point-n-shoot 
camera's have lenses that start at 38mm.  The biggest advertising point of 
these (and often the model number of the camera) is how long a telephoto 
it has.

I had to search around to find a P&S camera for my Mom that started at 
28mm, there were very, very few available.

I think it's a marketing thing, not a technology thing.

THAT'S why wide angle lenses are much more common on
even inexpensive 35mm cameras. Given the larger image
size, and no retrofocus design issues (because there's
no mirror), a 24mm compact 35mm lens is relatively
easy to design, and images on the film can be quite good.
